It is a fact im studying it and I know know this is a fact.
The mantle layer with more convection is the upper mantle, which has a higher temperature and undergoes vigorous convection currents. In contrast, the lower mantle has less convection due to its higher pressure and lower temperature, leading to slower convective movement.
The theory of plate tectonics states that the Earth's lithosphere is divided into several large plates that move over the semi-fluid asthenosphere of the mantle. The motion of these plates is primarily driven by convection currents in the mantle.
Mantle convection is the slow motion of the Earth's silicate mantle, caused by convection currents that carry heat from the interior to the surface of the Earth. Mantle convection causes the tectonic plates to move around the Earth's surface, causing earthquakes, tsunamis, and volcanic activity.
One prominent theory for the driving force of plate tectonics is mantle convection. This theory suggests that the heat from the Earth's interior causes the mantle to flow slowly, creating convection currents. These currents can push and pull tectonic plates, leading to their movement. Other contributing factors include slab pull, where denser oceanic plates sink into the mantle, and ridge push, resulting from the formation of new crust at mid-ocean ridges.
Waves is the part of convection current. This is the mantle and is related to plate motions.
Arthur Holmes theory was that the mantle under goes thermal convection.
The theory of plate tectonics explains the movement of plates by convection cells in the Earth's mantle. These convection cells are caused by the heat from the Earth's core, which creates movement in the semi-fluid asthenosphere layer of the mantle, leading to the movement of the rigid lithospheric plates above it.
Arthur Holmes 1928 theory described plate tectonics and a modern view of the solid Earth. He pioneered the use of radioactive dating of minerals, and understood the mechanical and thermal implications of mantle convection, which was a basis for plate tectonics.
The mantle layer with more convection is the upper mantle, which has a higher temperature and undergoes vigorous convection currents. In contrast, the lower mantle has less convection due to its higher pressure and lower temperature, leading to slower convective movement.
Convection currents rese and sink through the mantle and the liquid outer core. In Earth's mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself causes convection currents in the mantle.
Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in 1912. He suggested that thermal convection currents in the mantle cause the movement of continents over time.
The theory of plate tectonics states that the Earth's lithosphere is divided into several large plates that move over the semi-fluid asthenosphere of the mantle. The motion of these plates is primarily driven by convection currents in the mantle.
That is the current theory of plate tectonics.

Yes. It's true that slow movements of mantle rock called convection transfer heat in the mantle
Heating from the Earth's core drives convection in the upper mantle. This convection is extremely slow; the speed with which material in the Earth's crust spreads from the mid-ocean ridges is of the order of several cm per year. Nevertheless, it is evident that the same forces which drive convection in the atmosphere and in the ocean are present in the "solid" earth as well. Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface.
